With the new Beta i get a lower speed with the same setting witch i use with latest stable. With a fresh profile i get also the same lower speed. I have testet with Eweka and Newshosting always with 25 connections. Whene i set 50 connectios with the Beta i get also full speed. With the Beta i need now much more connections for the same speed.

Interesting. Can you give the download speed, preferrably for the 1GB and/or 10GB reference downloads?

So:
25 connections => speed X MB/s
50 connections => speed Y MB/s

FWIW: my results with Beta1:
1GB: 20 connections frugal, 8 connections eweka => 45 MB/s (which is my linespeed)

Which reference download?

In SABnzbd's upper right corner, click on the wrench symbol ("Status and interface options"), then click on first tab Status, and there click on "Test download" 1GB or 10GB.

Have test with 1GB (10GB the same) on Beta 1

25 connections => speed 24.2 MB/s
50 connections => speed 58.7 MB/s

With latest Stable:

25 and 50 connections => speed 59.1 MB/s

In Config, Specials, can you lower downloader_sleep_time to 1?
And then restart and try again?
Or even set it to 0.

Standard is 10 and i have test with 1 and 5:

25 connections => speed 24.2 MB/s

Could you check what happens if you set it to 5?
This is still new code for us so thanks for reporting and hope you can help us find the right balance!

Sorry my settings befor are wrong. I have forget set back from 50 connections to 25. I have corrected it above.

Now with 1 or 5 the speed is also slow. With 0 i get with 25 connections full speed.

That's unfortunate, but thanks for testing. This is kind of my fault. Which hardware plaform and operating system version are you using? Do you run it from source or a binary installation? Do you have or can you create an account at https://github.com? If so I can try to adjust the new code and a new binary you can download will be created.

safihre: Maybe try to increase the idle_count threshold so that it doesn't kick in as quickly? Alternatively, try to calculate it from the bps, for instance sabnzbd.BPSMeter.bps/10 000 000 (or maybe /5 000 000), so that it gets higher with higher bandwidth. On Windows and maybe some other OSes there is no difference if the downloader_sleep_time is set to 10 or 1 because the timer resolution is too low. From my tests I didn't expect it to be this limiting, but maybe other factors like round trip delay matters as well.

I use latest Windows 10 Pro and use the Windows Standalone (64bit) from Sabnzbd. I have a Account on Github.

I also found 3.2.0b1 to be slower, setting downloader_sleep_time to 0 helped a little bit but still not getting the 100M+ speeds I used to. Struggling around 60M.

This is on Win10 Pro using sab x64 binaries

I have made a change which may help. To try it, go to https://github.com/sabnzbd/sabnzbd/pull/1745, click the green V next to the commit hash (9babe8c), then click Details at "Build binaries and source...", then Artifacts and select Windows Installer to try it. You need to be logged in.

This is the change compared to the official branch: https://github.com/sabnzbd/sabnzbd/pull/1745/files

I'm not sure why it doesn't help to set the downloader_sleep_time to 0. Maybe it makes SAB spend too much time in the download loop instead of too little.

Which green V??

Sorry, it was the best description I could come up with. It's not an actual V, but the V-like symbol which shows that the tests were ok at the end of the commit line ("Try sleeping less often at higher speeds"). Not the header but the one below the empty description. Search for 9babe8c.

It's possible that this direct link works, but I'm not sure if the Artifacts dropdown will be there: https://github.com/sabnzbd/sabnzbd/runs/1669849965
